a housing having upper and lower ends, a bore extending vertically between the upper and lower ends, the vertical axis extending longitudinally through the bore;
a bearing outer ring disposed within the bore and coupled with the housing;
a bearing inner ring disposed within the bearing outer ring and having a central bore configured to receive a portion of the shaft, the bearing inner ring being sized such that the upper axial end of the bearing inner ring is radially aligned with the housing upper end;
at least one set of a plurality of rolling elements disposed between the bearing outer ring and the bearing inner ring and spaced circumferentially about the vertical axis;
an upper seal disposed about the bearing inner ring and within the bore externally of the bearing outer ring so as to be spaced axially above the rolling elements and adjacent to the housing upper end, the upper seal including an annular elastomeric seal body with a sealing lip; and
a lower seal disposed between the bearing inner ring and the bearing outer ring so as to be spaced axially below the rolling elements.
